8 EVOLUTION 1 SYSTEM MANUAL Issue Issue 1.1 20 Dec 2006
‘G’ 0x47 Errors (note: error codes must be reset)
(EV I, EV II, EV SC)
Q. ESC|STX|Address|`G`|SOH||EOT
R. ESC|STX|Address|`G`|'x`|`y'|EOT
Where: x defines bits 7,6,5,4
Bit 7 = UART Overrun Error
Bit 6 = Communication Overrun Error
Bit 5 = UART Framing Error
Bit 4 = UART Parity Error
Where: y defines bits 3,2,1,0
Bit 3 = Font checksum error loading from card to chip
Bit 2 = Font 1 checksum error in Ram
Bit 1 = Font 0 checksum error in Ram
Bit 0 = Real Time Clock Memory error
TO RESET ERROR CODES
D. ESC|STX|Address|`G`|'x`|`y'|EOT
same bit positions as above
use only as a mask to clear error bits.
i.e. x = 0001 and y = 0001 clears real time clock memory
error and UART parity error.
X. ESC|STX|Address|`G`|ACK|EOT
'R' 0x52 Head Status (read only)
(EV I, EV II, EV SC)
Q. ESC|STX|Address|`R`|SOH|EOT
R. ESC|STX|Address|`R`|`x`|`y`|EOT
Where: x defines bits 7,6,5,4
Bit 7 = Not Used
Bit 6 = Latched eye active
Bit 5 = Unfiltered eye active
Bit 4 = Product being printed
Where y defines bits 3,2,1,0
Bit 3 = auto repeat print gap active
Bit 2 = Not Used
Bit 1 = Input buffer Line 2 full
Bit 0 = Input buffer Line 1 full
'B' 0x42 Set Unit Address (Write Only)
(EV I, EV II, EV SC)
D. ESC|STX|Address|`B`|`x`|`y`|EOT
X. ESC|STX|Address|`B`|ACK|EOT
Where x y = 8 bit unit address
i.e. x = 0x31 & y = 0x35 yields unit address 15
